Abstract

The invention discloses an environment-friendly adhesive which is creatively characterized by comprising the following main components in parts by weight: 3-5 parts of isocyanate, 3-5 parts of a flame retardant, 5-10 parts of modified polydialkysiloxane, 6-10 parts of a polyurethane prepolymer, 5-20 parts of resin, 5-8 parts of silicic acid, 3-5 parts of a siloxane oligomer, 1-3 parts of an accelerant and 3-5 parts of a cross-linking agent. The environment-friendly adhesive has the advantages that by adjusting proportioning of the raw materials, the coordinative synergism of the raw materials is improved, and the prepared adhesive is nearly tasteless, wide in application range, simple in formula and easy to handle, and adopts a simple preparation method.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to an environment-friendly adhesive. Background technique [0002] Adhesives are one of the most important auxiliary materials. In general, adhesives (also called "pressure-sensitive adhesives") are in the state of soft solids (viscoelastic) in the temperature range around room temperature, and have The property of using pressure to easily stick to the adherend. Among them, acrylic adhesives are generally superior in light resistance, weather resistance, oil resistance, etc. compared to rubber adhesives, so acrylic adhesives are widely used in various fields for bonding, fixing, etc. . Adhesives are defined as non-metallic materials that can bond adherends by surface adhesion as well as internal strength. Adhesive is a viscous substance, which can connect two separated materials together by virtue of its viscous ability. There are many types of adhesives. The existi...
